The X-ray and IR spectra of metal-free phthalocyanine show that the x-form of HEPC is B-Pc. X-ray measurements of the B-form of MgPc reveal that alteration to the so-called a-form of MgPc occurs in air. Continued cycling of the sample between vacuum and air demonstrated the reversibility of this pro

## Abstract Thermal conversion of polyhexazocyclanes and compound modeling the fragments of polymers were explored within 300–600Β°C under vacuum (10^βˆ’5^ torr) and in water vapor. At temperatures below 450Β°C, the hydrolytic degradation plays a key role in the thermal degradation of polyhexazocyclane
